This application provides numerical solution 2 dimensional wave differential equation.
Wave is bounded in rectangular area. (boundary conditions of equation)
You may simulate behavior of wave which is set by several parameters
(number of segments in x and y directions, dx and dy growth, dt growth, damping factor, c1 and c2 constants)
, initial shape (initial conditions of equation) and additional boundary conditions of equation.
You must be careful when setting equation parameters. Too big values, or some
parameter values combinations may lead to numerical instability (for example: big nonlinearity
factor: 2.0 and much smaller other parameters).
Using application:
STEP1: you may change your equation parameters on Advanced tab
STEP2: you may change wave initial shape by tapping Define Shape
and changing this shape using your finger.
STEP3: You may add some boundary conditions by tapping Define boundaries
and tapping on places when you desire one.
STEP4: Start your simulation by tapping Start Simulation button.
During simulation You may choose between three ways of visualization (Visualise tab):
-spectral view
-3d chart view
-3d bar view
It is recommended to use tablet devices.
